I don't think there's any chance of him hitting 30 goals or thereabouts.
If this move does happen, it goes to show Pep/City threw everything into the Kane pool, only for it to backfire.
As Leonardo mentioned, I think this is just to show Mbappe their intention for next summer (not that they need to going by is supposed admiration for RM).
The outcome of this match will be very telling for what's to come.
With CIty's failed pursuit for Kane, we are title favourites by a slight margin, so a win over a fellow challenger would set a marker.
The Grealish situation is slightly different as he had a release cause, but I still believe they overpaid for him regardless. We tend to be shrewd in the market, so hope we pursue options elsewhere.
Their "four captains" have supposedly taken a pay cut or are in the process of doing so. Pique's decision was announced first, so Barcelona could register their new signings prior to the season beginning.
